I bought a boat that had 4 echomap 102s on it. The electronics did not come. With the boat. I bought two 106 and a 93 and used the existing network cables to hook up the three units. Initially could not get the pan optics to network to the two units at the drivers station. Somehow they started working. I got an sad card and tried to update the three units. The network was recognizing the three units and it updated the 93 but error Ed on the two 106’s. Now the pan optics is not being shared. Could it be that the 93 is updated and the 106’s are not? Tried to update the 106’s but no go. Do I need a separate sod card for each unit?

Which brand of electronics are they?
